Well I know why my wastegate came out sooo easily... The torque tube support was missing! The bracket is on the wastegate but it has nothing to connect to...

Would someone with a PET and knowledge of what the support is supposed to look like please check my numbers to make sure I'm looking at the right parts to order?

Looks to me like it should be:

951 123 155 02 and
951 123 179 02

plus the necessary bolts and washers... correct?

TIA

 

It appears you are. BTW - alot of guys run the much heavier TiAL without the support.

I wouldn't order the brackets - as Matt mentioned, many run without it with no problems, and more importantly, you'll save some money getting the brackets from one of the many people who went Tial.

Thanks for the quick reply (I love this forum for just that reason).

I'm tempted to run without it... seems to have been that way for quite some time. Any idea if there's adequate clearance to install the support/bracket with the wastegate already installed? In other words, go ahead and install the wastegate without the bracket and then put the bracket in later. I'm guessing NO, 'cause if one could, it would seem to be the easier thing to remove to pull the wastegate in the first place...

 

That bracket is just barely short of impossible to install and remove.

Sam

 

So pretty much like most everything else on our cars....

 

Nah, intake manifold, any brake part, tranny, turbo are all easier - I'd say it's on par with heater core.

Sam

 

Ouch!

 

May I offer a contrary opinion here? Yes, LOTS of people run without those brackets and have no problems. I am pretty weight conscious when it comes to my 951, but I prefer to have it installed. It makes the wastegate/exhaust assembly a lot more stable. As the assembly heats up and cools down, it will move a lot, and I would have thought it would fail more quickly without the support bracket there, altho I think I have been proved wrong by the many people who haven't had problems.

Its actually not that hard to install the bracket for the wastegate. I just did it last week and it took maybe twenty minutes, altho my car was already up in the air on jack stands. Once the wastegate is off the car, along with the dump tube to the cat pipe, orient the piece in place, start the top bolt, spin it so you can start the bottom bolt, spin back so you can tighten the top bolt so that its pretty snug, and then rotate it one final time so that the bracket is in place and snug it up. From there, put the wastegate AND the dump tube in place, and start all the bolts before tightening anything down. Its a little bit of a squeeze to get to the top bolts, but not impossible.

Regards,

 

Hey, you know what, Sam just mentioned something I totally forgot about. I HAVE a set of those sitting on the floor that arent going back in. You can HAVE them. PM me an address. I need to get rid of some of the ****e in my garage anyhow.

Scott - what do you want me to do with this AFM? Still need the airbox? I know bloodraven needs it when you are done.

Thanks for the generous offer Matt H. Just PM'd you.

 

That bracket that clamps to the torque-tube is a definite necessity. To install it, you want to have it lose so you can rotate and slide it on the torque-tube as you install the wastegate. As you wiggle the wastegate into place and clamp the front flange and rear V-band, you rotate the clamp to line up the holes. Once the wastegate's position is fixed, you tighten down the clamp on the torque-tube. Then bolt through the wastegate hanger to the clamp.

I've seen several cars that have had broken dump-pipes coming off the wastegate because of the flexing of the exhaust. The wastegate-hanger clamp will probably help limit this flexing somewhat , along with proper adjustments of the rear muffler hanger.

 

Since I'm not especially patient, does installing the wastegate without the clamp make doing so later impossible without removing and re-installing the wastegate?

(Note: for me this may be even harder, as I have the old, one piece cross-ver pipe (wastegate bolts directly to the pipe w/o the short piece w/ the flange)... it does have the Lindsey split mod, however...)

 

It shouldn't be a huge task for you to remove the wastegate to put the clamp on, and I doubt that running for a month or so would compromise anything.

Regards,

 

As he said, just install the wastegate now and put the bracket on when you get it - the bracket is the time-consuming part, so you won't waste any time on the wastegate itself.
